STOVE.

Specification of Letters Patent.

Patented Nov. 1, 1910.

To all whom it may concern:

Be it known that I, JAMES M. MnRRrrT, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new' and useful Improvements in Stoves, ofwhich the following is a specication.

This invention relates to improvements in sheet iron stoves, and itconsists particularly in the combination of certain features to producea more efficient and convenient arrangement, as will hereinafterappear'.

One of the features of the combination is a flat damper member for thetop of the rounded lid or cover, this damper member allowing a draftthrough the lid and also being flat for the placement of any articlethereon.

In the accompanying drawings, Figure 1 is a plan view of a stoveequipped with my device. Fig. 2 is a longitudinal vertical sectionthereof. Fig. 3 is an enlarged detail section taken on line 3 3 of Fig.l.

In the drawings 5 designates the body of a stove of usual construction,the body being supported on legs 6 and having opening 7 in its top nearits rear end for the escape of the gases of combustion through the pipeordinarily supplied. A second and larger opening 8 is located at thefront of the stove and cover 9 is adapted to completely close thisopening. At the front of the stove an opening 10 is controlled by ascrew damper 11, this damper being of ordinary construction. Leadin fromopening 10 is a downwardly extending flue 12 which terminates near thebottom of the front of the stove, the draft passing down through thisflue as is indicated by the arrows. A damper top 14 is provided forcover 9 and consists of a circular plate 15 which fits down upon the topof cover 9, the central and upper part of the cover being provided witha circular aperture 17 through which a flange 18 on plate 15 projects.Inside of flange 18 plate 15 is provided with a set of draft openings19. A rotating or otherwise movable member 20 is secured to plate 15, asby rivet 21, this member 20 also having a set of draft openings 22 whichmay be thrown into and out of register with openings 19 by means ofhandle 23. By this means the amount of draft throu h the cover may becompletely controlle As a means for lifting the cover, a swinging handle25 is provided, this handle having a bail 26 which is secured to thecover at each end by being turned in, as at 27, through an aperture 28in cover 9. This aperture is so arranged that the bail rubs against theedge of plate 15, the bail being constructed to spring inwardly againstthe plate. At points immediately above openings 28 groovcs 29 are cut inthe edge of member 15 so that, when the bail is in a vertical position,as shown in dotted lines in Fig. 2, it may spring into grooves 29 and bethus held in its vertical position.

The damper may be made in any contiguration and design as is desired. Inthe present design plate 15 is perforated as at 30 for the purpose oflightening the casting and for rendering it more artistic than a planesurface would be. This and other features may be varied to suit anyparticular case.

It will be seen that the draft induced by the combination of the twodraft openings will be something similar to that indicated by the arrowsin Fig. 2. The air and gases inside the stove will be set into a spiralor circular motion which will cause complete combustion with a minimumof draft passing out through opening 7. Thus not so much heat as isusually the case will pass out of the stove and be lost so far as allpractical purposes are concerned. The spiral motion allows the air tomore intimately come into contact with the fuel and thereby effectscomplete combustion with a minimum amount of air.

From the immediately foregoing, and from the following claim, myinvention is seen to consist in the combination of the devices toproduce a down draft from the front top of the stove and to produce ahot air draft from the front bottom of the stove, together with the:features of construction which assist the combination in making a stoveof practical utility and high efficiency.

Having described my invention, I claim A stove construction, comprisinga hollow body having a draft outlet at its rear upper end, an opening inits top near the front, and a draft inlet in its front near the top, adraft tube leading from the draft inlet downwardly on the inside of thebody to a point near the bottom, a damper controlling the draft inlet, abell shaped cover adapted to close the opening in the top of the body,the cover having a flat top and an opening in the center thereof, astationary recessed plate inountefl on the top of the @over and InWitness that I elaiin the foregoing I having draft apertures therein,and a movhave hereunto subscribed my name this 8th able plate mounted onthe stationary plate clay of JanuarylQlO.

n its recess and having apertures therein JAMES M. MERRITT. 5 forregistration With the apertures in the stationary plate, the uppersurfaces of both plates being flat and in the same plane.
